I am using a StrataFrame standard form but the form will not be bound to a BO.. But the form insists on assigning one of the BOs I have dropped on the form as the PrimaryBusinessObject and I dont want that... I'll set the PrimaryBusinessObject to (none) and then run the app and It will assign one of the BOs at runtime. Is there anyway to stop this?

What functionality are you looking for?  The form is still going to have one of the business objects set as the PrimaryBusinessObject, but it will not interact with any of the business objects because the IncludeInForm options are all diskabled.  If you don't want a business object to be set as the PrimaryBusinessObject, then you will need to set the PrimaryBusinessObject property to Nothing within the Load event of the form.
